[PATCH 3/3] tests: avoid unnecessary use of GIT_TRACE in repo-setup tests

[Jonathan Nieder <jrnieder@gmail.com>]

Now that the startup info is printed by a separate helper, there
is no need to mark that output with "setup: " or use an environment
variable to request it.

While we're changing the test-repo-setup output format, stop quoting
newlines to give the tests a chance of passing when $TEST_DIRECTORY
contains a newline or backslash.
